本発明は、自動車をはじめとする運輸車両用材料ならび
に建築用材料、電気機器用材料等に使用される防錆用鋼
材に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to rust-preventing steel materials used for materials for transportation vehicles including automobiles, materials for construction, materials for electrical equipment, etc.
従来、亜鉛または亜鉛を主体とする合金をめっきした鋼

、これらのめつき鋼板を成形後、りん酸塩処理してから
塗装するのが一般的でわる。Conventionally, steel sheets plated with zinc or zinc-based alloys have been widely used for rust prevention purposes, and this is based on the sacrificial anticorrosion effect of zinc. After forming these galvanized steel sheets, automakers generally apply phosphate treatment and then paint them.
ところがその際、鋼板の接合部近傍に生ずる形状の複雑

のの溶出を抑制する効果をもつ被覆をめっき鋼板上に施
すことが必要である。However, in this case, the coating does not reach the complex-shaped parts that occur near the joints of the steel plates, and the plated steel plates are exposed to a corrosive environment. In a galvanized steel sheet and a steel sheet coated with an alloy mainly composed of zinc, the zinc elutes rapidly in a corrosive environment in an unpainted state, and the rust prevention effect of the steel sheet cannot be maintained over a long period of time. Therefore, in order to improve the bare corrosion resistance of a plated steel sheet, it is necessary to apply a coating on the plated steel sheet that has the effect of suppressing the elution of zinc itself, which has a sacrificial anticorrosion effect.
そのため特公昭６０−３３１９２ 号公報のごとく、
めっき表面に有機樹脂に防錆顔料を添加したものを被覆
することが知られている。Therefore, as stated in Special Publication No. 60-33192,
It is known to coat the plating surface with an organic resin containing an anti-rust pigment.

This organic coated steel sheet has excellent corrosion resistance and is characterized by being coated with a thickness of 2.5 microns and hardened.

膜を形成した後のめつき銅板に塗布し、加熱により硬化
膜を形成する。For example, ladder-type silicone resin has the chemical structural formula shown below, and its chemical name is called organosilsesquioxane oligomer.It undergoes condensation polymerization by heating, forming a ladder-type structure and a bridge structure between ladders. A thermosetting resin that becomes polyorganosilsesquioxane. This oligomer is dissolved in an organic solvent containing an alcohol, an ester, a ketone, an aromatic compound, an organic compound similar to any of these, or one or more of these compounds, and then subjected to chromate treatment or sinate treatment, etc. It is applied to a plated copper plate after forming a chemical conversion film, and a cured film is formed by heating.

媒となるため、これらを用いることによりキュア（硬化

触媒効果が大きい上、亜鉛めっきを侵さないため、有用
である。) Since acids and bases act as catalysts for the condensation polymerization of ladder-type silicones, by using these, curing can be carried out at low temperatures and in a short time. In particular, cynic acid is useful because it has a large curing catalytic effect and does not attack zinc plating.

性能を更に向上させることも可能である。For example, when using a phosphoric acid catalyst, the film can be cured by baking at 180°C for about 20 minutes;
Even when half-cured for about 0 seconds, the film remains strong, and there is no blocking phenomenon when winding a steel plate coil, and there is no peeling phenomenon during press working. Therefore, it is also possible to further improve the corrosion resistance by curing in the painting and baking process after processing and assembly.

ウレタン系等の各種有機樹脂の添加も可能である。The steel sheet of the present invention has superior corrosion resistance in the resin itself compared to organic resins such as epoxy and acrylic resins.
It has sufficient corrosion resistance even without the addition of anti-rust pigments such as i02. Of course, antirust pigments may be added. Furthermore,
Various additives such as lubricity imparting agents and surface tension modifiers can be added as needed, and epoxy, acrylic,
It is also possible to add various organic resins such as urethane-based resins.

役割は、第一に、通常のクロメート処理またはシん酸塩
処理と同様、亜鉛めっきの耐食性を向上させることであ

を確保することである。The role of the chemical conversion coating such as chromate treatment or sinate treatment applied to the galvanized steel sheet before application of ladder-type silicone resin is to The first purpose is to improve corrosion resistance, and the second purpose is to ensure adhesion between the ladder-type silicone and the plating surface.

害される。The resin film thickness ranges from a minimum of 0.20 microns to a maximum of 2.5 microns.
It needs to be in the micron range. If it is less than 0.20 micron, the desired anticorrosive effect cannot be obtained sufficiently;
If the diameter exceeds microns, the pinholes in the resin will be completely filled even on a galvanized steel sheet with large surface irregularities, so weldability and suitability for electrodeposition coating will be significantly impaired.

果が得られる。The base chromate used as the chemical conversion coating can be any of the chromates normally applied on galvanized steel sheets or zinc-based alloy-plated steel sheets, that is, electrolytic chromates, coating-type chromates, and reactive chromates. Of course, chromates that are a combination of two or more of these can also be used. Furthermore, the desired effect can be obtained by applying sinate treatment to υ instead of chromate treatment.

の手段によシ生成することができる。Furthermore, when applying a multilayer plated steel sheet with two or more layers as the base, the zinc or zinc-based alloy plating layer does not necessarily need to be located on the top layer of plating, and the top layer plating can be subjected to the above-mentioned chemical conversion treatment. It suffices as long as it is a tanned layer. Specifically, for single-layer plating, zinc should be at least 60%, with the rest being the metals mentioned above, and in the case of two or more layers, the bottom layer should be at least 60% zinc, the rest should be the above-mentioned metal, and the top layer should be zinc 60% to improve chemical conversion treatment. % or less, the remainder may be a plating layer made of the above-mentioned metal. Of course, the plating layer can also be made of 60% or more of zinc and the rest of other metals. These platings can be produced by electricity, melting, or other means.
